FIELD: machine building.
SUBSTANCE: invention refers to gear transmissions of open and closed types. Application method of antifriction coatings to working surfaces of teeth of hardened gear wheels consists in the following: working surface of teeth of coated gear wheel (1) is cleaned from oxides by means of a metal brush; then, anti-friction material is applied by means of operation in the pair with gear wheel made from the applied antifriction material, for example aluminium. Sliding of working surfaces of teeth of matched wheels ensures the transfer of antifriction material.
EFFECT: invention allows increasing the service life of gear wheels.
